HVDROIDA II j(.g 



furnished with seven to ten broad, slightly prominent teeth. The oiDenin<r part curving more strongly out 

 between the teeth, we have a broad furrow running from the highest point of the teeth and continuing 

 some wa\- down the hydrotheca, where it disappears. The longitudinal axis of the hvdrotheca; is often 

 somewhat curved. The basal cavity is very small, l)Ouuded at the top b\- a sharjily defined, fairly 

 prominent ring-shaped thickening of the inner wall. 



The gonothecse are attached to the stolons by a short, often rudinientarv stalk. Thev are egg- 

 shaped to oval, attached to the stalk by their broad end, and running out distally to a fairly long, 

 narrow cylindrical neck. The gonothec;e are often slightly bent, and faintlv and irregularly wrinkled 

 transversely.

The above-noted synonym Campamdaria iiiag)iifica Fraser (1917 p. 164, pi. 11. figs. 1 — 3) ought 

 not really to require any further explanation. Fraser I1917 pi. 11, fig. 4) figures for purposes of com- 

 parison a gonotheca of Campamdaria spcciosa from Alaska; this is, like the one shown by Levin- 

 sen (1893 pi. 5, fig. 7) a developmental stage, only a little younger still. I have previou.sly described 

 the fully developed gonotheca after specimens from the Kara Sea (1912 p. 18 fig. 3I; the conformity 

 with Fraser's pi. 11 fig. 2 is e\ideiit. The other distinctive characters noted by Fraser are void of 

 all significance, as will be seen from a somewhat richer material of the species. 



Caiiipaiiiilan'a sprciosa is a panarctic species, belonging to the shallower parts of the littoral 

 region. Within the areas investigated, it is only known from West Greenland, where its most south- 

 erlv occurrence was noted on the Store Hellefiskebanke.

Creeping colonies, from the stolons of which proceed hydrotheca stalks, smooth, or more or 

 less distinctly ringed or spirally coiled, especially near their origin, and close under the hydrotheca; 

 the stalk here always terminates in a ball-shaped joint. The hydrothecee are large, inversely conical 

 to nearly cylindrical; the conical ones taper gently down throughout their whole length towards the 

 stalk; otherwise, the hydrothecse are rounded smoothly off at their basal part; every pos.sible kind of 

 intermediate form may be found. The hydrotheca margin is smooth, with no indication of teeth,
